90W USB 0B46994 0A36258 AC Adapter Charger for Lenovo ThinkPad T440 T550 T440S L540 E540 X250 T450s X240 E450 IdeaPad Flex 10 Z710,Fit ADLX90NLC3A ADLX90NDC3A ADLX90NCC3A ADLX65NCC3A[20v 4.5a]

When I first got the charger, it seemed like it was a perfect replacement. Unfortunately, after a couple of months, the charger is giving me difficulty in a finicky power plug.After a couple of months of pretty normal daily use, the power cord that plugs into the transformer no longer has a secure connection. Small movements of the power cord will intermittently connect and disconnect the power to the computer. There's no visible damage to the plug, and it's in a location where I would be hard pressed to stress the heavy-duty power socket or thick power cord, for that matter. See the photo for where the issue appears to be in the device.Edited Review: REO has contacted me and offered a replacement charger at no cost. This is gracious of them, and the 4/5 stars is for their customer service and the promise of a fully-working charger. When I get the replacement charger I'll correct any inaccurate information in this review and upgrade to 5/5 if the intermittent plug issue goes away, because overall the build quality looks quite good, with thick flexible cables.Updated 1 week after second adapter sent to me: Everything looks great. The second adapter's working just fine. REO's customer service was excellent - yes, they contacted me because of my negative review, but they were very responsive and replaced the adapter at no cost. I would order from them again.

The power adaptor is the right model in terms of the power input specs, however, the piece that you insert into the power adaptor slot on the Lenovo Z710 IdeaPad seems to be just a little bit larger that the adaptor's input piece. This causes the connection to be loose, but not faulty. It will still charge properly and stay in place if not moved around or jolted suddenly. Sometimes, if the laptop is moved slightly, it is necessary to push the adaptor back into the charging slot firmly so that it stays in place again. Once this is done, it goes back to charging normally. BIG TIP FOR USERS OF THESE CHARGERS: Do no bend the adaptor's wiring anywhere near the end of the charging cable. If you do this, the wires inside the cable will loosen and twist, causing the charger to slowly lose its capacity to charge properly over time. Keep the charging cable straight as much as possible at least 12" from the end of the AC adaptor.

I have only used my charger for my computer for a few times, but I am very pleased. I asked if it should be hot and the seller responded that some heat was normal. It doesn't get very hot and seems to power my Lenova Z10 very well. I use it when sitting in another room so I won't have to take my regular charger. By the way, the charger I use all the time came from Amazon and it is better than a genuine Lenova charger I had. I was very pleased with the reasonable price of this charger. I recommend the Reo Adapter Charger. It is a good bargain. I gave it four stars as I haven't had it very long and can't attest to its durability.

Great replacement power adapter.

I've had this charger for about a month now. The one day shipping was so convenient as I needed it on emergency after my original one started making a chirping noise indicating it unstable to use. This one does the job and is so much cheaper than buying my computer brand charger.

I got this for my wife's Lenovo Yoga-720 computer so she can have one charger at home and one at work. It works great, just like the original that came with the computer. We unplug the computer at night to not wear down the battery and the repeated plugging and unplugging has not affected the connection.

Works fine for Lenovo E570 ThinkPad. Plug slightly different from original and had to be firmly pushed in to make contact. Haven't used it long enough to rate 5 stars

Perfect charging cable for a backup of stuffing in a work/school bag.
